试图通过docker compose run创建一个docker和django

Question

你好，我是新来的docker，我有问题，让我的docker撰写文件正确运行时，我运行docker compose run --rm django django-admin startproject yuuera .它给了我一个错误

[floofyflare@ArchLinux dockercomp]$ docker compose run --rm django django-admin startproject yuuera .

我相信我的Dockerfile设置正确，但我不确定我的docker-compose文件。

version: "3.8"
services:
django:
build: .
volumes:
- .:/django
ports:
- 8000:8000
image: django:django
container_name: django_container
command: python manage.py runserver 0.0.0.0:8000
depends_on:
- db
db:
image: postgres
volumes: 
- ./data/db:/var/lib/postgresql/data
environment:
- POSTGRES_USER=admin
- POSTGRES_PASSWORD=...
- POSTGRES_DB=...
container_name: postgres_db

'我已经尝试禁用已经运行的PostgreSQL实例，我已经运行并改变docker-compose中的环境变量。但是没有成功。

这个问题的答案在Arch用户中很常见，这个github表单很好地解释了这个问题，它对我来说很神奇!不过，请确保您使用的gpg密钥位于根目录中，因为从根目录进行docker调用是很常见的。https://github.com/docker/docker-credential-helpers/issues/102 issuecomment - 1420315320

你也必须从根用户登录到docker，然后才能对用户进行任何涉及凭证的操作
